EZCH'MQND, VIRGINIA, ASSIG-NOR TO FIBEPROOF CONCRETE-BIO CK WALL CO1? STRUCTIOIV Application filed June 10,

This invention relates to concrete block wall structures, and has for its objects to provide a particular shaped concrete block, which, upon arranging a plurality of them in rows and tiers, will form a substantial wall and one wherein the bloclrs can be easily and effectually cemented together and be reinforced in a simple manner.

These and other objects hereinafter set forth are accomplished by the means illustrated in the accompanying drawing, in which:

Fig. 1 is a perspective view of a portion of a wall structure embodying my invention.

Fig. 2 is a vertical cross-structural view taken on the line 2-2 of Fig. 3.

Fig. 3 is a horizontal sectional view taken on the line 33 of Fig. 2. r

Fig. 4 is a perspective View of one of the slabs or blocks isolated from the wall and showing the arrangement of several of the reinforcing rods; and,

Fig. 5 is a detail perspective view of one of the transverse tie-members.

Similar reference numerals in all of the ligures of the drawing designate like parts.

As shown i 1, the wall is preferably composed of an inner wall and an outer wall 11 arranged in parallel relation and spaced apart to form an insulating air space between them, and it will be observed that the blocks or slabs 12 are arranged in horizontal and vertical rows with their joints in alignment in both directions, and that the walls are joined together by the tie-members 13 at the intersection of the vertical and horizontal joints.

Each block or slab 12 is formed at both its vertical edges with a projecting vertical ledge 1% which extends approximately the full length of the edges, and the bases of the ledges lie slightly back of the edges, and said ledges are concaved on their outer sides to form a recess, which when the edges of one slab is positioned close to the edge of an adj acent slab, will form a vertical pocket to receive a vertical reinforcing rod 15 and the uniting cement 16 which is poured therein to provide a vertical concrete column extending the full height of the Wall.

1829. Serial No. 369,843.

At the upper edge of the slabs is formed a projecting horizontal ledge 16, similar to the vertical ledges 15 and practically being a continuation of said ledges 14:, and having its upper side concaved to receive the horizontal reinforcing rods 17, so that, when the slabs are arran ed edge to edge, the concaves of the horizontal ledges will form a series of open gutters extending continuously across the wall and the concrete fillin 18 therein will embed the horizontal rods 1 and unite with the concrete of the vertical columns 16.

Tie-members 13 are precast and are of any suitable cross section in form, preferably rectangular, as shown in the drawing, and they are reinforced their entire length by a tie-rod 19 whose ends project a considerable distance beyond the concrete port-ion so that they can be tied to the rods 15 and 17 at their intersections, as clearly shown in the drawings.

The wall is erected by assembling the wall slabs in courses and after each course is laid, mortar or grout is applied to the hollow spaces between the walls and in the gutters formed by the horizontal ledges,thereby filling every joint and covering allof the metal reinforcing rods and ties, thus providing a wall construction which is easily erected and aligned and connecting firmly all of the oints 1 and sealing them on the rear sides.

It will be understood that each of the building units used is preferably precast and, if desired, with a finished face, so that a finished wall can be laid without the use of any other coating of plaster or the like.

The bed joint formed by the horizontal gutters is essential in that it provides a ledge to receive the sealing cement and it is obvious that the cement can be applied easily and without mechanical or artistic skill. The bed joint is also designed to assist in aligning the wall and at the same time provides a watertight joint.

Having thus fully described the invention,- what is claimed is:

1. A concrete wall construction formed with a plurality of precast concrete slabs laid in superposed horizontal courses with their vertical joints in continuous alignment, a

vertical concrete column extending the height of the wall formed at the vertical joint between the slabs and between the meeting edges thereof, and a plurality of horizontal 5 rows of concrete material formed in horizontal alignment with the horizontal meeting edges of the slabs and lying to the rear of the body portion of the slabs.

2. A concrete wall construction having inner and outer walls and each formed with a plurality of precast concrete slabs laid in superposed horizontal courses with their vertical joints in continuous alignment, a Vertical concrete column extending the height of the wall formed at the vertical joints between the slabs and between the meeting edges thereof, a plurality of horizontal rows of concrete material formed in horizontal alignment with the horizontal meeting edges of the slabs and lying to the rear of the body portion of the slabs, each of said vertical columns and horizontal rows of concrete material being provided with reinforcing rods which intersect at the intersection of the joints between the slabs, and transverse precast tie-members located at the intersection of the rod joints and formed with a reinforcing rod whose free ends are tied to the intersecting portions of the horizontal and vertical rods.

3. A precast concrete slab for wall construction, comprising a slab-like body portion having two parallel edges enlarged and formed with a recess to provide a hollow space between adjacent slabs, another edge of the slab being formed with a projecting ledge on the rear side and said ledge being recessed at its outer sideto provide a horizontal guther to receive a concrete filling positioned at the rear side of the wall.

In-testimony whereof I aflix my signature.
